Design and Simulation of Smoke Alarm System Based on 51 Microcontroller with LCD1602 Display (Proteus Simulation + Program + Design Report + Schematic + Explanation Video)
Simulation software: Proteus 7.8 or above
Compiler: Keil 4/Keil 5
Programming Language: C
Design Number: S0068
Main Functions:
The smoke alarm system based on the 51 microcontroller features:
1. The LCD1602 displays the smoke alarm value and the detected smoke value;
2. The alarm concentration can be adjusted using buttons;
3. When the smoke concentration is below the alarm value, the green indicator light is on.
When the smoke concentration exceeds the threshold, the buzzer alarms and the red indicator light is on;
4. The ADC0832 collects the voltage changes of the sliding potentiometer simulating the MQ-2 sensor.
Note that the microcontroller chip in the simulation is compatible; the AT89C51 and AT89C52 are specific models of the 51 microcontroller, with the same core. In the same schematic, whether STC or AT, the pin functions are the same, and the programs are compatible, allowing for replacement with STC89C52/STC89C51/AT89C52/AT89C51 and other 51 microcontroller chips.
